Question
Two groups are present in monosaccharide: carbonyl (C=O) and alcohol. For aldose numbering starts from the carbonyl C going to CH2-OH. For ketose numbering starts from the C nearest the C=0. Classification of Monosaccharide 1. Based on carbonyl group Aldose (aldehyde) Ketose (ketone) 2. Based on the number of carbon atoms (triose, tetrose, pentose, hexose, heptose, etc.) 3. Combination of 1 and 2 (ketotriose, aldotetrose) ACTIVITY-1. Which of the following is NOT a monosaccharide? Explain your reasoning. A В Но ÇH2OH СООН 0= Но H- Но H. НО H- HO H. но H. НО H- Но H.
